Thanks for the replies, Part of the issue is I do not have the mill completely square, and it was cutting without stuttering, but I was tightening the tolerances and started losing steps due to friction.
Gene, my driver is a CMD-50c which can handle 15-40v, and 3.5 amps, but I do not have access to anything above the 19v I currently have. Thanks for everything, it looks like I will be looking for other motors. The z-axis is 4 in and works alright, but the y-axis at 14 inches is underpowered, and the x-axis at 30 inches hardly moves without stuttering. Chris, I did change the step output to be inverted as you suggested, and no noticeable change in speed. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
